Installation
Sageon II 200A (N+1) Power Distribution System
PM990-5202-200, Rev. 6
2-14
Installing the Sensors:
1.
Open the distribution door and locate the multiple battery temperature board. Locate the coiled
sensors.
2.
If not already connected, plug the battery temperature sensor connectors and the ambient temperature
sensor into the controller backplane board. See Table 2-4 for the connectors and Figure 2-6, 2-11, and
2-12 for a view of the board. The connectors are keyed.

3.
Select a location for mounting the ambient temperature sensor ring lug. The temperature of this mass
should have a fairly long thermal time constant (e.g. temperature should not cycle with short-term
temperature changes due to normal environmental heating and cooling cycles).
4.
Fasten the ambient temperature sensor to the selected point using appropriate user-supply hardware.
Typically this could be the equipment rack the Sageon 200A system is mounted in.
5.
Route the 4 battery temperature sensors to the battery string(s). Typically somewhere close to the
string midpoint.
6.
Determine which battery posts will have sensors attached. Suggested location is shown in the adjacent
battery string drawing.
Note: The highest of the four battery temperature readings is used for compensation. Locate a sensor
at the warmest battery, generally one at the center of a battery group.
7.
Determine the charge/discharge status of the battery string. Connecting the sensors may result in a
momentary battery string open circuit when the terminal bolt is removed.
CAUTION: DO NOT
proceed if the battery string is being charged or discharged at a high rate.
Continue only when the charge or discharge rate is at a safe level.
8.
Remove the bolt holding the inter-cell battery strap in place. Insert the bolt through the battery
temperature sensor ring lug, through the strap, and into the battery terminal. Tighten the bolt as
recommended by the battery manufacturer.
9.
Repeat steps 7 and 8 to install the remaining battery temperature sensors.
10.
Bundle and secure excess wiring.
11.
Enable compensation using the operator panel push buttons and menus or a PC running Sageview.
12.
If installing the sensor kit, get the compensation chart label. Remove the backing from the label and
place the label on the inside of the distribution area door.
